Don't swim, bike, run, jump, climb, throw or kick without thinking about Timex Ironman Triathlon Performance Sport OVA Watches.
OVA = Optimal Viewing Angle and this innovation means the watch is designed to be worn on the inside edge of the wrist so that it can be read without the need to turn the wrist.
When you think about it, that is where every watch should be when you have your hands full trying to test your body to the max on foot or on bike and any switch of body movement can only upset your balance and efficiency.
